I found about GIMX a month ago when a colleague of mine was selling his Logitech G25 for next to none price. I use GIMX to emulate G25 as G29 on PS4.

At first I just made a DIY adapter with Teensy2.0 clone and cheap CP2102 bridge, plugged it in on Windows 10 machine and it worked seamlessly.
I immediately tried the RPI version, which also worked great.
I am currently working on plugging Teensy to RPi's built in UART because I want everything in the same box.

After I am done with that, I hope to contribute by making and sharing configurations for some other, less known controllers I have laying around.
